TNT is absolutely safe for human use.
We recommend applying it to your boots or shoes, socks and lower pant legs as these are likely the first places ticks access. If you will be in a wooded area where ticks are on brush or trees, you can apply it to your upper body apparel as well. TNT it is safe enough to be used in your hair, where it may be difficult to notice ticks. It will wash out easily.
Hikers and hunters are among our best costumers. TNT does not have any odor so it does not interfere with hunting and can be applied around and on tree stands very cost effectively to keep ticks from hiding there.
The TNT Puffer sold on this site will direct the TNT powder down into your shoes and socks, and throughout your hair.
Because TNT is a powder, it is drying and can irritate eyes and noses. If you are sensitive to powder or have asthma like issues we recommend you wear goggles and a mask while applying it. Any irritation is temporary. (More about this under our Safety Policy page.)
